tailed description of the saine. r Referring now to Figs. 1 to 5 ofthe said S0 With the various objects of the present indrawings, the reference character 7 indicates vention in view, the saine consists, primarily, the. complete novel construction of self-fasin a cup shaped back-plate. to which is secured teninug button made according to and eni in overlying relation, the button-face shell tob odying the principles of the present inven-` gether with its fabric covering when usedthe tion the saine comprising a cup shaped back 85 bottom of said back-plate being inwardly conplatevhaving. an inwardly concaved bottom 8 cavedand having spaced prongs struck outprovided with 'angularly' spaced sectorial wardly therefrom, said prongs being shaped apertures uniformly spaced around the and arranged so that the apertures,v produced center porti'onof said bottom and arranged i0 in said bottom upon the formation of said so as to provide nietal portions extending 9c prongs, are not continuous but are boundedby from Side to Side O Bald bwk-plate. .Tile metal portions extending from side to side of sectorial apertures 9 are formed by striking said back-plate, thereby providing a strong outwardly V-sliaped prongs '10 arranged diback-plate'construction. Said prongs by beametiically opposite one anotherand pro ing arranged at the periphery of said baclr- )ecting from the periphery of said bottom 95 plate may be well spaced so as not to weaken 8. rhe presence of the apertures 9 cause the button supporting fabric by their inserthe bottoni 8, in the preferred f orin, to have tion therethrough. rlfhese prongs are clinched a cruci-foim s hape as viewed in plan, (see upon an anchor member that is inwardly con- Fig. 5) and this conformation together with caved to conform to the concaved bottom of the concave-convex shape of the bottom 8 100 in section cause this bottom to possess great strength and rigidity which is desirable in order for the bottom section to retain its effective grip upon the Afabric l1 under all conditions of stress. It will be understood, however, that less or more than four prongs 10 and corresponding apertures 9 may be employed.

The prongs 10 have sharp points 12 which enable these prongs to be readily pressed through the body of the fabric 11 from the outer to the inner surface thereof. The portions of prongs 10 that project beyond the inner surface of the fabric 11 are adapted to be clinched over an anchor member 13. Anchor member 13 is of substantially annular shape and its diameter is less than that of the back-plate or bottom section so that it may be inserted between opposite prongs 10. The anchor member 13 is of concavoconvex cross-section and its inner convex surface 14 confoi'nis to the concave under surface of tlie bottom 8. With the prongs 10 clinched upon the anchor member, this member presses against the inner surface of the fabric 11 underlying the bottom 8 and forces the outer surface of this fabric into intimate frictional contact with the bottom 8. Owing to the compression of the fabric by the anchor member, portions of this fabric are forced up into the apertures 9 causing the cruci-form bottom 8 to be imbedded somewhat into the fabric, resulting in a greatly increased gripping action of the backplate and anchor member forming the button bottom section or fastening means upon the fabric and serving to prevent the pulling out of the fabric from between the members 8 and 13 regardless of the foices applied to the button 7.

rIhe back-plate is formed with a peripheral flange 16 extending upwardly from the bottom 8 and this fiange has an outwardly offset upper portion 17 arranged in gripping relation with the button top section. This button top section comprises the button-face shell 15 having a covering cloth oi fabric 18 which is tucked under the 1depending edges of the shell 15 and is retained in position thereon by the frictional grip of the flange 17. It is evident that the button-face shell 15 may or may not be covered with cloth and may be made in many ways and of many designs.

Referring now to Fig. 5, there is illustrated therein, a slightly modified form of anchor member. In this figure, the anchor member 20 is of substantially disk shape and has concave-convex faces for conforming to the concave surface of bottom 8. This anchor member 20 is of substantially the same form as anchor member 13 with the exception that no central aperture is provided in member 20. The concave outer surfaces of anchor members 13 and 20 enable the prongs 10 to be bent into hook shape inwardly of the outer periphery of the anchor members (see Fig. 4) so that these prongs secure a better grip on the anchor members. The points 12 by being deflected inwardly are prevented from catching on or tearing clothing etc., that may be rubbed past the inner surface of the cloth or garment 11.

It will be noted that the novel self-fastening button of this invention is of simple construction, having two maiii parts, a top section comprising essentially the button-face shell 15 and a fastening means or bottom scction comprising the back-plate and the anchor member gripping opposite sides of the fabric. Owing to the positioning of the prongs l0 at the periphery of the back-plate, these prongs may be well spaced so as not to weaken the fabric as a result of their insertion therethrough. Also, this construction enables the use of an anchor member of maximum area which together with the concavo-convex nature of these elements and the presence of the sectorial apertures results in an exceedingly rigid grip of the button or the fabric or garment. Also, since the prongs l0 extend over the outer periphery of the anchor inember, a maximum area of fabric is gripped by the fastening means, thereby preventing the pulling out of the button and enabling the use of a disk shaped anchor member when desired.

As many changes could be made in the above construction and many apparently widely different embodiments of this invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings s hall be interpreted as illustrative and not in a limiting sense.

What is claimed is 1. A self fastening button having a top section and fastening means therefor comprising, an anchor member, an apertured back-plate having outwardly struck prongs arranged around the circumferential periphery thereof, said prongs being adapted to extend through a supporting fabric and clinched radially inwardly over the outer peripheral edges of said anchor member, the apertures in said back-plate being produced upon the formation of said prongs, said apertures acting in cooperation with said prongs and said anchor member to secure said button to the supporting fabric.

2. A self fastening button having a top section and a bottom section, said bottom section comprising a cup shaped member having symmetrically arranged sectorial apertures in the bottom thereof, and V-shaped clinching prongs projecting from the circumferential periphery of said cup shaped member,

said apertures being produced by the strik- 13 ing out of said prongs from the bottom of said member.

3. A self fastening button having a top section and a bottom section, said bottom section comprising a cup shaped member having sectorial apertures in the bottom thereof, said bottom being of concavo-convex shape, V-shaped clinching prongs projecting from the periphery of said cup shaped member, and

lo an anchor member adapted to be clinchedby said prongs.

4. A self-fastening button having a top section and a bottom section, said bottom section comprising a cup shaped member having sectorial apertures in the bottom thereof, V-shaped clinching prongs projecting from the periphery of said cup shaped member at the bottom thereof, and an anchor member,

said prongs extending over the outer periphery of said anchor member and clinched upon the exterior surface of said member.

5. A self-fastening button having a top section and a, bottom section, said bottom section comprising a cup shaped member having a concavo-convex bottom with sectorial apertures therein, V-shaped clinching prongs projecting from the periphery of said cup shaped member, said sectorial apertures being produced by the striking out of Vsaid prongs from the bottom of said cup shaped member, and a concavo-convex anchor member conforming to the concave under surface of said cup shaped member and retained in cooperating relation with said under surface by said clinching prongs.

6. A self-fastening button having a top Y section and a bottom section, said bottom section comprising a cup shaped member having a cruci-form bottom with a concave under surface, an anchor member having a convex upper surface for cooperating with the concave under surface of said bottom to secure said button to a supporting fabric, and lugs extending downwardly from the periphery of said bottom section and clinched inwardly over the outer peripheral edges vof said anchor member.

In testimony that I claim the invention set forth above I have hereunto set my hand this 13th day of March, 1929.
